Improved bed-bottom



J'Or'rN DECYAMP, .OF OINOINNA'TLOHIO.

Letters Patent No. 95,329, dated September 28, 1869.

IMPROVED- BBD-BOTTOM.

The Schedule referred to in thse Letters Patent and making 'part ofthesame pgw--L- To whom, it may concern; y

Be it known that I, JOHN DEGAMP, of .Cincinnath Hamilton county, Ohio,have invented 'a new and useful Bed-Bottom; and I hereby declarethe-following to be a'full, clear, and 'exact description thereof,reference being had to the accompanying drawings, mak'-4 ing part ofthis specification.

My invention relates to the class of bed-bottoms in which a series ofwooden slats are supported upon spiralsprings,and consists in va simpleand effective mode ot'attaching the springs and. slats, without the yuseof any wovenor fibrous fabric, such as webbing,

straps, cords, andthe like, which are objectionable because of theirliability to harbor'verminkbesides being Very` destructible andcapableof attachment in the manufactory only, thus making it impossible toseparate the parts for package, cleansing, or transl portatiomascan bedone with my arrangement. l

My invention also dispenses with the use of any lat- 4eral strap orbrace, whether of wood, metal, or other material. v

' The construction being also such as to bel capable of being quicklytaken to pieces and put together again by any person of ordinaryintelligence, or of being readily reduced in size to fit a'ny particularbedstead.

Figure 1 is a perspective view of a bed-bottom embodying my invention.

Figure 2 is a transverse section of the same.

Figure 3 is a section on an enlarged scale through one of'the springs,with its accompanying nut.

Figure 4 is a perspective View ofthe nut.

A .A A are three bearing-rails, whose ends are in-` tended to rest inrebates 4in the side rails of the bed- Resting upon, and attached tothese rails areas many series of 'spiral springs, B", -of the customarytruncated conical form, except that their upper extremities C passvertically through apertures din the slats D, and are screw-threaded toreceive nuts, E, somewhat concave or dished, or with aprojecting margin,c, on their under sides, and wings e on the upper sides, with which toturn thenut by hand.,

The spring has its base or large diameter to' the rail, and supports theslat upon the upper coil.

lThe nuts Eenable all the parts ofthe bottom to bei` in a few minutesunited in `one compact.. and s tanch, yet elastic whole, without the useof any tool whatever, or any mechanical skill and the flat and roundedupper contour of the nut prevents Wear o f the mat tress, while itssharp and salient lower margin gives' it a firm'and stable attachment tothe Slat. f

The nuts are preferably of metal, but maybe 'of hard wood, or itsequivalent, and may, if desired, enter recesses or countersinks in thetops of the slats. The number of rails, slats, and series of springs maybe greater or less, as may be desired.'

It is intendedthat thesprings'n this form'of bottom shall be of suicientstiffness to supersede theI necessity offwebbing or A other lateralstays. About No. 7 wire makes a good spring'for this purpose.

i In order to put this bottom together, it is merely necessary to passthe upper ends of the springs through the apertures d, and fasten thesame by the nuts E, an operation that can be perfolmed by the thumb andfin er.

hould the bottom be too large for the bedstead, it

can be easily fitted to it without 'any detriment, by

simply shortening off the rails or slats, as the case may be.

For transportation or removal, the bottom may be in'a few minutes takenapart, without any tool Whatever, and put in one or more 'very compactparcels.

This bottom is equally elastic in every part,-and laffords no harborwhatever for vermin, nor is it liable to getout of order by use;

I claim herein as new and of my invention- The combination of the slatsA D, the spring B, screw O, and dish-formed or concave lnut E c,provided with wings e", all constructed and arranged as and for thepurpose set forth.

In testimony of which invention, I hereunto set myhand.
